What a New Roof Installation Includes

Every full installation we sell covers the whole assembly, not just the visible surface. Here is what comes standard, and what we quote separately so there are no surprises on the invoice.

Full Tear-Off and Disposal

We strip the old roof down to the sheathing and haul every pound of it away in our own dumpster. That includes old underlayment, flashing, and fasteners. You do not rent a dumpster or make a dump run.

Deck Inspection and Repair

Every board gets checked for rot, delamination, and nail pops. We replace damaged sheathing and re-nail the deck to current code before anything goes on top. Decking repair is priced per sheet and approved with you before we proceed.

Underlayment and Flashing

Synthetic underlayment or roofing felt goes down over the deck, with ice-and-water membrane in valleys and around penetrations where code requires it. Chimneys, skylights, and vent pipes get new flashing and roof sealant.

Ventilation Balance

We install ridge vents and verify soffit intake is open and sized correctly. Balanced ventilation protects the warranty and keeps attic temperatures down. If your intake is blocked or undersized, we tell you before the shingles go on.

Permit and Inspection Handling

We file the roofing permit with your city or county, pay the fees, and meet the inspector on site. Any correction notice is our problem to fix, not yours. You get the final inspection sign-off in your records.

What Roof Installation in California Actually Involves

Roof Installation in California is the full tear-off and replacement of your roof system, or the first-time install on new construction, covering decking repair, underlayment, flashing, and the finished surface. We start by stripping old material down to the sheathing, replace any rotted sections, then lay roofing felt or synthetic underlayment before the first shingle or panel goes down. Every penetration, valley, and ridge gets flashed and sealed to California Building Code standards.

Most homeowners call us after a leak, a storm, or a home inspection flags curling shingles and cracked flashing. Others are building new and need a California roof installation contractor near me who can pull permits and pass Title 24 energy checks without delays. In the Valley, sun damage cooks shingles from the top down. Along the coast, salt air eats fasteners and flashing. We spec materials for the conditions your roof actually faces.

From the first call to the final walkthrough, here is what you can expect when we install a new roof on your home.

Schedule

Call or book online — a real human picks up and confirms a 2-hour arrival window.

Diagnose

Licensed tech inspects on-site, then walks you through the cause and your options.

Fix

The job is completed to code and done right the first time — no shortcuts, no surprises.

Guarantee

Every job backed by a written workmanship warranty — and we stand behind it.

Tools and Methods We Use on Every Roof

Tools & Equipment

Roofing nail gun

Drives shingle fasteners to the correct depth and pattern at speed. We set compressor pressure per manufacturer spec so nails seat without tearing the mat.

Shingle cutter

Cuts clean edges at valleys, hips, and rake lines. Cleaner cuts mean tighter laps and fewer spots for wind to grab.

Roofing safety harness and ladder stabilizer

Keeps crews tied off on steep pitches and keeps ladders from shifting on gutters. OSHA-compliant fall protection on every job, no exceptions.

Nail magnet

Sweeps the lawn, driveway, and flower beds for stray fasteners. We run it twice, and again after the dumpster is pulled.

Caulking gun

Applies roof sealant at flashing edges, pipe boots, and counterflashing. We use sealants rated for UV exposure and thermal movement.

Chalk line and pry bar

Chalk lines keep course alignment straight across long runs. Pry bars lift old flashing and shingles without damaging the decking underneath.

Methods & Standards

California Building Code (CBC) compliance

We install fastening schedules, flashing details, and fire classifications to CBC requirements. Inspectors pass our work because the details match the code book, not because we got lucky.

Title 24 Energy Code cool-roof compliance

In climate zones that require it, we install cool-roof rated shingles and tiles that meet the solar reflectance index. We document the product rating for the permit file so inspection does not stall.

GAF Master Elite and Owens Corning Preferred installation

As certified contractors, we install these systems to the manufacturer's exact specification, which unlocks the top warranty tiers. That includes starter courses, ventilation, and fastening patterns.

OSHA 10 and OSHA 30 jobsite safety

Crew leads carry OSHA training, and every job runs fall protection, ladder safety, and debris control. A safe site is a fast site, and it keeps your family and pets out of harm's way.

When You Need a New Roof Installed

You are building a new home and need the roof installed before drywall.

What we do: We handle Roof Installation in California for new construction, coordinating with your general contractor on decking, underlayment, and inspection timing. We pull the roofing permit and schedule around your framing and rough-in milestones.

→ Your roof is dried in on schedule, the inspection passes, and your GC keeps the build moving without a roofing delay.

A home inspection flagged the roof before your sale closes.

What we do: We inspect, document with photos, and quote the repair or replacement the buyer's lender will accept. If the deal needs a fast turnaround, we schedule the work and provide warranty paperwork for the closing file.

→ You close on time with clean paperwork, or you negotiate from a documented position instead of a vague inspection note.

Storm damage tore off shingles and your insurance claim is open.

What we do: We tarp the roof the same day, photograph all damage, and provide a written scope your adjuster can work from. Once the claim is approved, we install the new roof and bill the approved amount.

→ Your home stays dry through the claims process, and the replacement matches what the adjuster approved without out-of-pocket surprises.

Your roof is 20 to 25 years old and you are planning to stay in the home.

What we do: We assess remaining life, then install a full replacement with a manufacturer-backed warranty and upgraded ventilation. You pick from asphalt shingles, tile, or metal based on budget and the look you want.

→ You get decades of service life, lower cooling costs from proper ventilation, and a warranty that transfers if you sell.

How Roof Installation Runs Across California

California roofs live in wildly different conditions, and the assembly has to match. Coastal homes from Daly City to Newport Coast deal with salt air that corrodes fasteners and flashing, so we spec corrosion-resistant metals and inspect pipe boots closely. Inland homes in Fresno, Fontana, and Ontario face summer attic temperatures that cook shingles from below, which makes balanced ventilation and cool-roof products non-negotiable. Foothill and wildland areas need Class A fire-rated assemblies and ember-resistant detailing at eaves and vents. Permitting varies by jurisdiction too. Some cities issue roofing permits in three days, others take two weeks and require a Title 24 reflectance form with the application. We know which offices want what, and we file accordingly. If you are comparing bids for a new roof installation California wide, ask whether the contractor has pulled permits in your specific city. That single question separates the pros from the storm chasers.

Neighborhoods We Serve

Canoga Park

Many 1950s and 1960s ranch homes here still have original decking, so we plan for sheathing replacement and check for skip sheathing under old tile.
Pacoima

Summer heat in the northeast Valley shortens shingle life. We push reflective shingles and ridge vent upgrades on most re-roofs here.
Wilmington

Port-adjacent air carries salt and industrial fallout. We use corrosion-resistant flashing and inspect fasteners closely on every tear-off.
Palo Alto

Older homes often have steep pitches and original redwood decking. We hand-inspect each board and match historic profiles where the city requires it.
Costa Mesa

Coastal fog and marine layer moisture make underlayment quality critical. We install synthetic underlayment as standard on these roofs.

Local Conditions We Plan For

Inland heat zones above 100 degrees in summer

Shingles age faster and attic ventilation becomes critical. We spec cool-roof rated products and verify intake and exhaust are balanced before sign-off.
Coastal salt air and marine moisture

Fasteners, flashing, and pipe boots corrode years earlier than inland. We use corrosion-resistant metals and check every penetration during installation.
Wildland-urban interface fire zones

Class A fire-rated assemblies and ember-resistant vents are often required. We confirm your zone designation before ordering materials.
Winter rain concentrated between November and March

We dry in each roof daily and schedule tear-offs around storm windows. Emergency tarping runs 24/7 when a system moves in mid-project.

Torrance Composition Roof Replacement

Before

A 1,900-square-foot ranch had a 22-year-old composition roof with granule loss, three active leaks, and soft decking around the chimney. The homeowner was patching every winter and losing ground.

After

We tore off, replaced 11 sheets of sheathing, and installed architectural shingles with new flashing and ridge vents. The roof was dried in on day two and finished on day three. Two rainy seasons later, no leaks.

Maintenance: Clear gutters each fall and have the roof inspected every two years. Coastal homes benefit from a fastener check at the five-year mark because of salt exposure.

Before

A 2,400-square-foot home had dark shingles baked to the mat and no ridge ventilation. Attic temperatures hit 145 degrees in July, and the AC ran constantly. Two prior patch jobs had failed.

After

We installed cool-roof rated shingles, added ridge vents and edge intake, and replaced cracked pipe boots. Attic temps dropped by roughly 35 degrees at peak. The homeowner reported about $60 per month in summer cooling savings.

Maintenance: Keep soffit vents clear of insulation and debris. Check ridge vent screens annually for dust buildup, which is common in the Central Valley.

Before

A pre-sale inspection flagged cracked tiles, rusted valley flashing, and missing underlayment on a 1960s home. The sale was 30 days out and the buyer's lender wanted documentation.

After

We pulled the permit, replaced underlayment and valley flashing, and matched replacement tiles to the original profile. Inspection passed on the first visit, and warranty documents went into the closing file. The sale closed on schedule.

Maintenance: Walk the roof after large storms to check for cracked tiles, and keep tree branches trimmed back. Tile roofs last decades when the underlayment and flashing are maintained.

Roof Problems We Solve for California Homes

Most roofs fail in predictable ways, and each one has a specific fix. Here is what we see most often and how we handle it.

Problem

Recurring roof leaks after patch jobs

Water keeps finding new paths through failed underlayment and cracked flashing, staining ceilings and soaking insulation. Repeated patches cost more than a replacement over three or four years.

Our Fix

We trace the leak to its actual entry point with a water test, then repair the flashing and underlayment around it. If the surrounding roof is at end of life, we tell you honestly and quote a replacement instead of selling another patch.

Problem

Curling and missing shingles from sun damage

Inland California heat bakes shingles from the top down, and wind gets under curled edges and tears them off. Exposed underlayment then fails fast, and the leak shows up inside within one rainy season.

Our Fix

We replace damaged shingles and re-seal where the roof has life left. When more than a third of the surface is curled or granule-bare, replacement is the better spend, and we install reflective shingles rated for high-heat zones.

Problem

Clogged gutters causing roof rot

Debris dams water at the roof edge, and it backs up under the first course of shingles. Fascia and decking rot from the outside in, and the repair grows from a gutter cleaning into a carpentry job.

Our Fix

We clear gutters and downspouts during every job, then check the roof edge for soft spots. Rotted fascia and drip edge get replaced before new roofing goes on, so the new roof has sound wood to fasten to.

Problem

Poor attic ventilation cooking the roof

Trapped heat and moisture warp decking, bake shingles from underneath, and void some manufacturer warranties. Attic temps can run 30 to 40 degrees above outdoor air in summer.

Our Fix

We balance intake and exhaust with correctly sized ridge vents and soffit vents. On older homes with no intake at all, we add edge vents or a powered option and verify airflow before sign-off.

Why Homeowners Choose Professional Installation

A roof is a system, not a stack of shingles. Get the layers, ventilation, and flashing right and you add decades of service life. Cut corners and you are chasing leaks for years.

Manufacturer-Backed Warranties

We install GAF, Owens Corning, and CertainTeed systems as certified contractors, which unlocks the strongest warranty tiers those brands offer. Material defects and workmanship are both covered, and we register the warranty in your name before we pack up. That paperwork matters at resale.
Correct Attic Ventilation

Poor attic ventilation bakes shingles from underneath and drives summer cooling bills up. We balance intake and exhaust with ridge vents and soffit vents sized to your square footage. A 1,500-square-foot attic typically needs about 1 square foot of net free vent area per 150 square feet of attic floor.
Storm and Fire Ratings

California roofs face wind, hail, and wildfire exposure depending on where you live. We install Class A fire-rated assemblies and shingles rated for 110 mph winds where code or HOA rules require it. That can matter for insurance eligibility in foothill and wildland zones.
Clean Site, No Surprises

We tarp landscaping, run a nail magnet over the yard and driveway twice, and haul away every scrap of old roofing. Most residential tear-offs are done in one to three days. You get a written price before we start, and the number on the invoice matches the number on the quote.

What Roof Installation Costs in California

Roof pricing in California comes down to square footage, pitch, material, and how much decking needs replacing. Typical 2026 residential tear-offs run $9,500 to $28,000. Asphalt shingles sit at the low end, tile and standing-seam metal at the high end, with flat TPO and modified bitumen systems in between. We quote the whole job, including permit fees and disposal, so the number you approve is the number you pay.

Typical Investment Range

$9,500 - $28,000 depending on size, material, and decking condition

A roof is one of the few home upgrades that pays you back in lower cooling costs, avoided water damage, and resale value. We give you a firm price, a real schedule, and a registered warranty, so the money you spend stays spent.

What changes the price

Roof size and pitch

Square footage drives material and labor. Steep pitches above 8/12 slow the crew down and require extra fall protection, which adds labor hours. A 1,500-square-foot ranch prices very differently from a 3,000-square-foot two-story.

Material choice

Asphalt shingles are the most economical. Clay tile, concrete tile, and metal roofing panels cost more in material and labor but last longer. Flat systems like TPO membrane and modified bitumen fall in the middle range.

Decking condition

We price decking repair per sheet, approved before we install it. Homes with original 1950s sheathing often need more replacement than newer builds. We photograph every bad board so you see what you are paying for.

Layers to remove

A roof with two or three old layers costs more to tear off and dispose of. We always recommend full tear-off over layering, because layering traps heat and hides decking problems.

Permit and inspection fees

City and county fees vary across California, and some jurisdictions require additional Title 24 documentation. We include the fee in your quote and handle the filing, so there is no separate bill later.

Verified Reviews

Google ★★★★★4.9

Crew showed up when they said they would, tore off our old roof in a day, and had shingles on by day three. They found two soft spots in the decking, showed me photos, and the price matched the quote. Yard was cleaner than when they started.

Yelp ★★★★★4.8

We had a leak over the kitchen that two other roofers could not find. RoofPros water-tested it, found a cracked pipe boot, and fixed it the same visit. They also flagged that our ridge vent was blocked. Honest work, no upsell.

BBB ★★★★★4.9

Handled our insurance claim after storm damage. Tarped the same night we called, documented everything for the adjuster, and installed the new roof once the claim cleared. No out-of-pocket beyond our deductible.

Google ★★★★★5.0

Needed a new roof before selling our Palo Alto home. They pulled the permit, passed inspection first try, and had warranty paperwork to our realtor within a week. Closing went through without a repair credit.

Cities We Serve for Roof Installation

Our crews install roofs across California, from the Los Angeles basin and the San Fernando Valley to the Central Valley, the Bay Area, and Orange County. Each region gets materials and ventilation spec'd for its climate, and we handle the local permit office in every city we work. Here is a sample of where we install.

Canoga Park

Ranch homes and mid-century builds with original decking. We plan for sheathing replacement and install cool-roof shingles rated for Valley heat.

Pacoima

Northeast Valley heat shortens shingle life fast. We spec reflective shingles, add ridge ventilation, and check every pipe boot during tear-off.

Sunland

Foothill homes near wildland zones need Class A fire-rated assemblies. We confirm your zone designation and install ember-resistant vents at eaves.

Wilmington

Port-adjacent salt air corrodes fasteners and flashing. We use corrosion-resistant metals and inspect penetrations closely on every installation.

Fresno

Central Valley summers push attic temps past 140 degrees. We install cool-roof rated shingles and balance intake and exhaust ventilation on every job.

Inland Empire heat and wind exposure. We install wind-rated shingles and verify fastening patterns meet the local inspector's requirements.

Ontario

Mix of tract homes and older builds. We handle permit filing with the city and schedule inspections around your workday.

Torrance

Coastal marine layer moisture makes underlayment quality critical. We install synthetic underlayment as standard and check flashing at every wall junction.

Costa Mesa

Fog belt homes see year-round moisture. We inspect decking for rot, replace damaged sheathing, and seal every penetration with UV-rated sealant.

Daly City

Cool, damp coastal conditions. We focus on underlayment integrity and flashing details that hold up to constant marine moisture.

San Leandro

Bay Area homes with a mix of composition and flat roofs. We install both pitched systems and TPO membrane for low-slope sections.

Newport Coast

High-end coastal homes with tile and standing-seam metal. We match profiles precisely and use corrosion-resistant fasteners throughout.

Frequently Asked Questions About Roof Installation

Real answers to the questions we hear most often from local homeowners and property managers.

Talk to a real pro: (877) 409-4846

How much does roof installation cost in California?

Typical 2026 pricing runs $9,500 to $28,000 for a full residential tear-off, depending on size, pitch, and material. Asphalt shingles sit at the lower end, while clay tile and standing-seam metal land higher. Flat roofs with TPO membrane often fall in the middle. Two-story homes, steep pitches, and decking repairs add cost. We give you a firm written number before any work begins.

How long does a roof installation take in California?

Most homes are done in two to four working days. A simple 1,500-square-foot ranch with asphalt shingles can wrap in two days. Larger homes, tile roofs, or jobs with significant decking repair stretch to five or six days. Rain delays are the main variable. We dry the roof in each day before we leave, so your home is never open to the weather overnight.

What is included in a new roof installation in California?

A standard new roof installation California homeowners receive from us includes tear-off, disposal, deck inspection and repair, underlayment, flashing, ridge vents, the finished surface, permit filing, and city inspection. Gutters get cleared and the yard gets magnetic-swept for nails. Warranty registration is handled before we leave. Skylight replacement and solar panel removal are quoted separately.

Do I need a permit for roof installation in California?

Yes, almost every California city and county requires a roofing permit, even for a like-for-like replacement. The permit protects you at resale and triggers the inspection that confirms the assembly meets code. We file the paperwork, pay the fees, and meet the inspector on site. You do not have to visit the building department or chase down signatures.
